T at whom it mag concern:

Be it known that I, SAMUEL D. RUTH, a citizen of the United States, residing at Beatrice, in. the county of Gage and State of N ebraska, have invented anew and useful Paper and Envelo Feeding Attachment for ype-Writers, 0 which the following is a specification.

This invention relates to devices of that type employed for feeding envelqps, postal cards, or slips of paper to typewriting H18,- chines, and has for its principal object to provide a device of simple construction which may be readily attached to or removed from anordinary form of typewriting machine, and further to provide mechanism whereby the feeding means may be quickly thrown into and out of gear, in order to stop the feed I when necessary.

A further object of the invention is to imrove and simplify the construction of the eeding mechanism, and a still further object j the same on the line 22 of Fig. 1.

is to provide a novel form of holder that may be readily adjusted to contain envelops,

cards, or slipsof different length.

With these and other objects in ,view, as

.will more fully hereinafter appear, the-invention consists in certain novel features of construction and arrangement of parts, hereinafter fullydesc'rib'ed; illustrated in the accompanying drawings, and particularlypointed out in the appended claims, itbeing 'understood that various changes inthe form, pro portions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention. 1 In the accompanying drawings :Figure 1 is a sectional plan view. ofan-envelop feeding attachment constructed in accordancewith the invention; Fig. 2 is a vertical section of,

I Fig. 3 is a rear'- elevation of the attachment showing the arrangementofthe feeding-rollers and their gearingconnections. Fig. 4 is an end view looking from the right of'Fig. 3.

Similar numerals of. reference are em ployed to indicate corresponding parts thrdughout the several figures of the drawin s. The present invention relates to feeding devices of that general type shown and described in Letters Patent of. the United from a gear on the shaft of the roller platen, as described in said Letters-Patent.

The casing 18 of the attachment is preferably rectangular in form, and is supported by a number of brackets 17, which are attached to the typewriter carriage.

' The casing, is preferably formed-of metal, and is provided at its lower rear edge'witlra discharge slot 19, the width-of which may be regulated by an adjustable false bottom 20, sliding on the bottom member of themain casing, and. provided at its rear edge with upturned lugs, to which are swiveled the inner ends of screws 21 that pass through openings formed in the front wall of the casing, and by adjusting these screws, the width of the delivery slot may be accurately regulated in accordance with the thickness of the envelops, postal cards, or slips of paper to be fed.

' Arranged within the casing is a plate 22, that is forced toward the rear by acompression spring 23, and the envelope or other articles to be fed are placed between this plate and the rearwall of the casing, and are forced by the spring tightly against such rear wall.

I The plate 22 and the front plate of thecasing-are provided with slots 25 for the passage of rods 26.. -These rods are provided with collars 27 that bear against the inner face of the front wall of the casing, and the outer ends of' the rods are threaded for the reception of milled or knurled nuts Whichinay be clamped tightly against the front of the casing for the purpose of firmly locking the rods26 in any position to which they may be adjusted. Theserods are adjustable toward and from each other to accommodate envelops, postalcards or'slips of paper of different lengths, and in order to hold the articles from independent longitudinal play, so that all may enter at the same point in the length of the roller platen.

' At a point below the discharge slot 19 is a pair of rollers 29 and'30, having shafts 31 and 32 respectively, the shaft 31 having fixed :00

bearings in the frame or casing, while the shaft 32 is engaged by leaf springs 33 which tend to force the shaft 82 in the direction of the-shaft 31, and thus keep the two rollers'in' intimate contact, so that positive feed of artir05 cles will be assured. These rollers are connected by intermeshin gears 34, although in some cases the ears wfilnot be necessary.

Secured ri hfiy to the shaft 31 is a sprocket States granted to meon December 12, 1905, No. 807,321, and is designed to be operated wheel 36, an pivoted to the shaft is'a swing- ITO-H- the ame 37 which may be swnng'on shaft 3 l for the purpose of enga ing or disengaging thepini ens and gear. n order to lock .the P1111011 in its engaged or disengaged position, the outer end of the frame 37 is provided with u,- piv'oted rod 4-2tl1atextends through a suitable opening formed in a boss i3 projecting from one side-of the casing, and said boss has a threaded opening for the 'ass'age of a clamping screw id which may e forced into on v ement with the rod for the purpose of loo 'n'g-s'aid rod in any adjusted position. In this manner the pinion may be readily moved toward or from-the gear of the roller platen, and'may bequickly locked in operative or inoperative positions.

Projecting from the rear of the frame are two sets of cars 4E748, and these cars have bearing openings for the reception of shafts 49%., respectively. The shafts carry discharging rollers 51 and 52 that may be formed of wood or of rubber, or of other suitable material, and preferably are rovided with projecting pins 53 which positlvely engage with the envelo s or cards and force the same between the "eed rollers 29 and 30. The-shaft 49 of the lower discharging roller is provided with a sprocket wheel 54, that is connected by a link belt 55 to a sprocket wheel5 -7 on the end of a shaft 31, so that the lowerdischarging roller maybe positively driven at all times.

. It is not in all cases essential to ositively drive upper roller 52, but in or er toprovide: for such ositive operation when necessary, the she t 49 carries a loose sprocket wheel 58 that is connected by a link belt 59 to-asprocket wheel 60 on' the shaft 50 of the upper when The lower sprocket. wheel 58 may be locked to the shaft 49 by a clutch 62, that is-un'der the control of an operating 10 ver 63, fulcrumed on a lug 64 at one side of the frame, and the construction is such that the clutch may be readily moved to looking or release position as may be required by the character and size of the articles to be fed.

Iif'the device is used for addressing purposes the movement of the roller platen. necessary for the placing of the name and ad- .dresson different lines of one envelop will opthe's'everal'ieed rollers, and the second L dr an out to a we, 1'espondin to the extent of movement of the platen, on in withdrawing the addressed envelop, the platen will be operated, and the second of the envelops will be fed to feeding position. In order to prevent contact of the envelop, or paper, with the bottom of the casing, when said envelo or paper is dis charged from the front 0. the roller platen, deflecting guides are secured to the lower front portion of the casing, and are extended rearward to a point adjacent to the front of the roller platen.

I claim:-

1. In a feeding attachment for typewriting machines, a casing, feed rollers for discharging articles therefrom, a gear on the shaft of one of the feed rollers, an adjustable frame pivotal-lymounted on the shaft and arranged to swing in a verticalplane, a short shaft at the free end of said frame, a driven gear carried by saidshort shaft, and a sprocket wheel and link belt connection between the short shaft and the feed roller shaft, whereby move ment may be imparted to said feed rollers.
